5-4 Chapter 5: BIOS Updating Procedures

BIOS Crisis Recovery

The procedures below provide a way to restore the BIOS resulting from a non-recoverable condition.

Note: Use this BIOS crisis recovery procedure only for a NON-RECOVERABLE BIOS failure. A non-recoverable BIOS state typically results from power loss during a flash BIOS update process. This is a rare occurrence and should not be confused with other hardware errors that cause a no video state. This procedure is not intended to be used for changing or upgrading an operational BIOS.
